Since I'm finally getting around to installing the new fuel line set I bought from Rob Grady at DCS, I decided it was time to look into one of the mods I've been wanting to do for a couple of years. I think I saw someone do something similar, so I don't think it's an original idea.
My goal was to eliminate the leak-prone o-ring setup for the idle control where the steel tube meets the metering unit. The pictures speak for themselves, but essentially I'm shortening the tube and using hose from the steel tube to this barb. Should be leak-proof and completely unnoticeable unless you were looking for it. Three plan is to TIG weld the new barb to the housing.
